No matter how technically illiterate ordinary consumers in most countries of the world were, they are still smart enough to add 2 + 2, because. it is enough to compare the markup on RAM and SSD as part of laptops and separately with a 5-10 year warranty to understand that laptop manufacturers brazenly charge lazy consumers who are not able to install a memory chip themselves and change, add an SSD, 200-400% markup for the same, but with a guarantee most often of 1 or at best 2 years, compared to 5-10 at retail.
It should also be taken into account that the buyer evaluates the old premium models, based on the fact that their characteristics are the same as at the time of the first reviews. But this is most often no longer the case by the time of purchase. Including Samsung. And almost everyone knows about scandals with AData models like 8200 Pro - where the performance in new batches was consistently worsened relative to the first reviews.

It may also turn out that the old product is BETTER than the new model in terms of quality, if you are lucky to take it from the old, very first batches, for some reason lying around in warehouses. And this changes everything...

Otherwise, such a product is clearly not worth the requested money. This is where most naive buyers come across. And this is exactly what cunning arbitrators are counting on, that the bulk of buyers on the planet take everything on faith (as in politics), and do not check the goods upon purchase. The procedures for refusing the goods and returning the goods are as complicated as possible and furnished with artificial obstacles, when the buyer nevertheless discovers a clear forgery regarding the level of quality expected from advertising and reviews and tries to take action ...
